Old Trades Lookup API limits lowered without notice?

Hello Binance Dev Community,

Today, I noticed that the old trades lookup /fapi/v1/historicalTrades endpoint limit was lowered to 500 max without any notice. Yesterday it was 1000, and today I noticed my bot stopped filling in missing minutes so it stopped all trading.

It is even painful to fill hours of raw historical trades for cold start my trade bot, without any way to fetch inner day data in bulk, why did this change happen even without any notice?
